today I tried to create a new Stage Plot on my Samsung Galaxy S3 Tab. (It runs Android 7) I pressed the + button and the new layout appeared. I give it a name and go to the layout section.But when i try to add a microphone or an instrument there is no icon appearing on the screen.It just adds the text to the list at the top of the screen, but no graphical icon is there.Is this a bug, or am I doing something wrong?
